The status quo of the domestic LED lighting sad independent innovation high voice

Real situation of domestic LED industry is currently using LED lamp industry, for example, most of the losses of the enterprise, but few enterprises are generally due to the loss of traditional business support. Despite the pain, but the thought of a huge piece of pie China several thousand billion market can eat, and, if the packaging enterprises flicker well, but also can be listed cashing investors money. Taking into account the Chinese government on the future of LED lighting prospect never hesitated, but will also introduce a series of supporting LED lighting industry development policies and support measures, the thought of this, these entrepreneurs heart and delicious. Anyway, the Chinese government's money is easy to flicker, simply swollen face fat man, continue to flicker, bet on it! This is the status quo of China's LED lighting industry - suffering endured, happy fantasy. But there is no serious thought: where does the pain come from? How to eliminate and alleviate the pain? Chinese government in support of LED lighting demonstration, can be said to be in support of the governments of the world's largest. Ten City million light demonstration project has been thrown into the billions of dollars. But the actual results? Many run for several months due to severe attenuation of LED street and had to be removed, although some lights are still burning in, but has been gradually dim, in order to face, still holding the dead! It is said that a well-known domestic enterprises street lamps, sent a team of hundreds of people throughout the country, fire maintenance. People can not help but ask: what is the reason for all these losses? Think carefully, hateful hateful is: China has become a number of so-called advanced developed countries LED lighting test field! While many LED street lamp production enterprises, although the victim, but also being kept in the dark. They are also proud to preach: we have won nearly 2000 km of LED street demonstration project! "These companies have become a tool for some foreign companies to make money from the Chinese government and taxpayers. Because of a business promotion: we use is imported * * * * company's famous brand LED light source, the price of up to thirty yuan per watt. This means, we have a one hundred watt LED lamp six thousand or seven thousand yuan price is not high! Our government according to each pay six thousand yuan, a few years later, 2000 km of the street, you need to pay more than and 10 billion, while foreign companies will * easily take 50%. with a little knowledge of semiconductor knows, LED wafer manufacturing cost is extremely low, making the foreign advanced technology, the low cost. The use of foreign LED light source mode of thinking to do the LED lamps, the outcome can be imagined. Foreigners want to ah: anyway, the Chinese government is now a lot of money, spend some money does not matter, China's enterprises are reluctant to spend money to develop it? Then you can take the money to buy a lesson! When the Chinese finally understand, a large number of foreign exchange has been made by foreigners. And our government officials and some experts and scholars, and even more entrepreneurs, but also ocean claiming: our LED lamps are imported light source ah! It can be said that the entire industry has been fooled by foreigners! Because foreigners began to sell to the Chinese people a packaged LED light source, on this point alone, the entire industry is going to detour. Because no matter what you are manufacturing plants, no matter how high your technology, as long as you use this LED light source to do lamps, you must be based on the characteristics of the light source to design LED lamps. Thus, China was born with dozens or even hundreds of the same structure of the LED light source composed of LED lighting fixtures. The structure of these lamps is basically the same, the LED light source of LED crystal is encapsulated in a heat sink, the light-emitting surface by resin lens package protection and make the light angle, dozens, hundreds of pieces of this light source is mounted to a printed circuit board and aluminum plate, aluminum is mounted to a whole radiator. On. In order to do a good job with light, the LED light source with a PC or PMMA material made of the lens, commonly known as "peanut lens" and then in order to waterproof and dustproof, and had to add a glass lampshade to do a good job sealing. Or not "peanuts lens with light, with a reflective coating on the housing cover, into a LED light source cavity for reflecting light distribution. And then loaded on the drive power supply wiring, power, LED lights, everyone is happy. "High tech" LED lamps developed so successfully! But the lights lit up after a period of time to find the problem. The internal temperature is too high, too much light, less than a few months as tens of percent decline. So all manufacturers are racking their brains, do everything possible to find ways, how to reduce the LED light source to the LED heat sink, to install the printed aluminum substrate, the thermal resistance between the radiator. So, nothing to do, only with low thermal resistance heat conduction glue filling. However, the low heat resistance of the conductive glue where? Only foreigners have. Therefore, the manufacturers at all costs to buy, even if it is a few dozen dollars a gram of the high price to buy ah! Who would have thought that this was a hard earned by foreigners! Overpaying, lamp resistance has decreased, but the decline is still serious! The foreigner said, do you Chinese lens PC, PMMA the material is too poor, easy to aging decay, and only our foreign material. Then, the manufacturer and a lot of imported PC material, PMMA, that it can reduce the light. As everyone knows, regardless of imported glue, or imported PC material, can not fundamentally solve
